Abstract

The main objective of this work is to comprehend the origin, causes and consequences of water shortages in Mexico for the best use of rainwater. The need for a rainwater collection method confronts social and environmental problems caused by water deficiency.

Concern about water scarcity in various regions of the country not only affects the amount of water available for present generations, but also for future ones; where the impact of climate changes, decreased rainfall, and human activities are causing a shortage of drinking water. Collection, filtration and storage of rainwater are being proposed for use.

In this work, filtration tests were performed, using activated carbon, suggesting a neutrality and slightly alkaline (pH7-8) for its usage and reduction of microorganisms. It can now be used on cleaning activities such as flushing toilets and washing cars, among other activities.

It should be noted that it is not for drinking or brushing your teeth because algae and microorganisms are found, which could cause gastrointestinal diseases. However, this filtered rainwater can be treated to make it drinkable with the UV light method or the Chlorination method.

Thus, rainwater collection represents a contribution to the recovery and use of water, it also replaces 40% of the water used in homes while being self-sufficient and environmentally friendly.
